Why Do We Need a New OSS/Orchestration in Open RAN?
August 8, 2021

Open RAN is a highly disruptive technology that will bring many benefits to Mobile Network Operators (MNOs), especially during the evolution to 5G. By opening up the RAN to multiple vendors and virtualizing the software, costs will be significantly reduced, highly dynamic services will be enabled, and the RAN domain will experience far greater levels […]

What is the difference between EPC,EPC+ and 5GC?
July 24, 2021

The core network is the most important domain in the mobile network starting from 2G and 3G while the MSC and SGSN are the main functions there to EPC or Evolved packet Core, then EPC+ in 4G network and finally 5GC or 5G Core in 5G Network. However, there are many differences between EPC, EPC+, […]

5G Security Vs. 4G Security
July 18, 2021

5G Timeline and Standardization  During preparation, it was decided to split Phase 1 into two parts. In December 2017, standardization of the non-autonomous, or Non-Standalone, architecture for 5G New Radio (NR) was completed. This first official set of 5G standards defines the wireless air interface for interworking with existing LTE-based networks. This has allowed operators […]

What does 5G Cloud Native means?
June 24, 2021

What is Cloud Native? In general, “cloud-native” is an approach to building and running applications that exploit the advantages of the cloud computing model. One key attribute of “cloud-native” is how the system creates and deploys applications. According to the definition of CNCF, “cloud-native” means that an application is containerized and uses an open-source software […]

3GPP Releases 16 Features
June 22, 2021

The evolution of 5G New Radio (NR) has progressed swiftly since the 3GPP standardized the first NR release (release 15) in mid-2018. Not only is release 16 nearly finalized but the scope of release 17 has also recently been approved.  3GPP plans to evolve 5G in three phases: Phase 1 – 3GPP Release 15 provided […]

Why Open RAN is Important?
June 21, 2021

If we’re talking about RAN Market Status, The mobile RAN equipment market (covering active base station equipment and antennas, but excluding power supplies, cable, install costs, civils, passive antennas, etc.) was worth about $33 billion in 2019, according to Omdia, and is forecast to grow to $36 billion in 2023.  So the R&D in different […]

What is the difference between 4G Core and 5G Core?
June 15, 2021

In LTE Core Network, all data plane traffic must go through a single node type called Packet Data Network Gateway (P-GW). This centralized architecture is advantageous in terms of operation and management. Yet, it could potentially pose a severe limitation when there is a huge amount of backhaul traffics in 5G. The following figure illustrates […]

Simplified Architecture for a Cellular Network
June 8, 2021

The device connects over the Radio Access Network (RAN), which defines and manages the radio link between the customer device and the rest of the network. The RAN comprises cellular base stations (BTS in 2G, NodeB in 3G,eNodeB in 4G, and gNB in 5G), wired or wireless links, and a baseband unit that processes the […]

Zain’s 5G network also went live […]

What is DSS or Dynamic Spectrum Sharing – Part 2
May 11, 2021

As we discussed in the last article, let’s Recap again What is DSS and why we need to use the DSS feature in 5G Roadmap deployment. Due to the occupation of its FDD-based spectrum assets, service providers are forced to choose between the acquisition of a new spectrum or refarm spectrum already in use. Both […]

What is DSS or Dynamic Spectrum Sharing – Part 1
May 6, 2021

Before start talking about DSS or Dynamic Spectrum Sharing, let’s address the problem first and how DSS can solve it. As we know that 5G can support newly released frequency bands for use – such as the C-band (3-5 GHz) and millimeter wave (mmWave) band (24-40 GHz) – are higher than the current 4G frequency […]
